Oil immersed Distribution Transformers 6-10kV

1. Introduction

6-10kV oil-immersed distributiontransformers with capacity 30-3150kVA are suitable for 6-10kV distributionnetwork system. Product complies with GB/T6451-2008 standards.

Type 9, 11 and 13 are classified byloss standard. Two types of oil tank are provided, they are sealed corrugatedradiating and sheet radiator. Voltage can be adjusted with load through switchinstalled.

2. Characteristics

Fully sealed corrugated tank has corrugatedsheet for transformer oil natural cooling. There is no oil storage cabinetneeded, so the oil is completely isolated from air. This design slows down theaging of oil, eliminates maintenance and extends the transformer life.

Q:Hi, I need a High Frequency( example~200khz) High voltage(200 000v) power supply at low microcurrent, I know that a Tesla coil fits the bill very easily . But I need to manually VARY the frequency(say from 100khz to 200khz ) while keeping the High voltage the same? Is this possible, Can some one guide me where I can buy or build this? Can I just for instance connect just a van de graaf or a rectified Tesla Coil to a function generator? If not what do I need to do to achieve what I want? I have been searching without help so your support is much appreciatedThanks: The Tesla coil needs to operate at the same resonant frequency on both the primary and secondary sides of the loosely coupled transformer. The resonant frequency is set by the inductance and capacitance of each side. The problem is there are no high voltage solid state capacitors (varactor diodes like you see in r.f. receivers that adjust the tank circuit frequency) on the primary side, and no way to adjust the top hat toroid capacitor on the secondary side (unless maybe it was a mylar covered balloon with vacuum deposited aluminum that could be remotely inflated or deflated). So you are stuck with whatever high voltage capacitor and toroid top hat you have on hand, and the inductance of the coils you wind that ends up being the resonant frequency. Even then it takes a lot of fiddling to get both in tune to give the maximum voltage output. The input frequency to the primary coil (the 555 circuit used in the step up with the flyback transformer- its frequency was chosen solely due to the flyback's frequency design) has little to do with the primary's resonant frequency; again that is set by the capacitor used and the size and number of turns of the primary coil.

Q:I have 14 gauge wire and some 28 gauge wire. Do both lengths of wire have to be insulated? Is it as easy as winding the 14gauge wire top to bottom and then do the 28 gauge wire top to bottom also? I'm guessing this is a step up transformer because the battery is going through the 14 gauge wire and then the lightbulb is hooked to the 28 gauge wire?Does the direction on winding matter at all? Say, CW for the 14g and then CW with the 28 gauge?: ferrite rods are not customarily used for transformers. at RF they are sometimes used as a core for a loop antenna. your application sounds like an ignition coil as you need an interrupter on the DC input (like points on a car ignition). the primary wire (14 gauge) would just be a few turns and not likely to run the full length top to bottom, the secondary (28 gauge) would be a lot of turns like 10 or 20 times as many. direction of winding would not matter in this application as capacitive coupling between the windings should be insignificant. all wire has to be insulated as a shorted turn spoils the transformer effect. wire used for transformers is customarily insulated with lacquer as plastic adds too much bulk to make tight windings. if you already have bare wire, then you made have some success by dipping the wire in lacquer paint first. it sounds like you are duplicating a project you have seen elsewhere. without knowing the source, it is hard for us to guess what the circuit parameters need to be for the transformer. but as i pointed out initially, i am skeptical that you will get this to function in the manner you are expecting. AC power transformers of the kind that use these wire gauges always use a torroidal core ferrite, never a rod. static DC cannot be transformed at all.

Q:What is the M of the transformer capacity MVA?: MVA with a table of his capacity, read: trillion volts in which M with a sign The conversion unit is 1MVA = 1000KVA = 1000000VA

Q:I want to get all the DVD'S for the transformers animated series and i was wondering how man series there are and what all they are called. if you could just give me the names of the series and tell me if they are on DVD or not. thanks for the help!!!: It comes on after Ben 10 AF so i desperate to computer screen Transformers lively sequence, just to furnish it a attempt, and the 1st factor I had a concern grow to be with the animation It grow to be all uneven, and it did not look that great i'm not into the paintings form the two, and the villians are poor!! i would be trustworthy and say the teach seems low-budget, and wasn't theory out nicely I recommend, you have this impressive Transformers action picture, and you will possibly anticipate the lively sequence may well be great impressive (rather with all of the money they have) yet no, it purely sucks. it would be cancelled, heavily. it quite is purely horribly lively, and poorly made.

Q:Single bus sub-section for power distribution, transformer with a prepared and dual-use how to understand: One with one: single bus segment switch closed, only one transformer power supply, another standby. Dual use: single bus section switch off, two transformers were powered. Added: Single bus segment wiring form, it is a single bus with sub-section breaker into several sections. Increased reliability and flexibility compared to single-bus non-segmentation. Advantages: 1, two bus segments can be split operation, can also run side by side; 2, important users can be connected to a different dual-circuit busbars, to ensure uninterrupted power supply; 3, any bus or disconnector overhaul, only stop the paragraph, the remaining sections can continue to power, reducing the power outage range.

Q:Can a transformer alone be used for amplifying audio signals ? If yes how ?: Transformers are AC (alternate current) devices and if 60 Hz is supplied to the primary windings 60 Hz will be produced at the secondary terminal. The transformers transform voltage and current at the primary to voltage and current at the secondary by magnetizing a mass of iron in their cores. The magnetic cores may not respond efficiently to very high frequencies (transmission frequencies) but might respond to audio frequencies (loud speakers employ magnets and coils of wire). If a suitable audio signal was applied to the primary coil a transformer might be used to step up or step down the voltage of the supplied signal while reversing its phase, however power (P EI) would remain nearly constant.

Q:How do step up transformers obey the law of conservation of energy?: I often end up submitting the same question on other sites

Q:i bought transformers a few months ago, and i finally watched it last night.my nephew watched it and i guess got something on the dvd.i was at the ending where they rolled bumblee in on the truck and the cube was destroyed and all that and optimus prime was saying they lost a great ----- i can't remember extactly what he said.anyway, right after that, the cd skipped and went do directly to the credits.what did i miss?: I am Optimus Prime, and I send this message to all autobots taking refuge among the stars. You are not alone.

Q:how low voltage smelting transformer can be modified to a higher voltage to be used in ferronickel production: You need to provide more information about the original use of the transformer. Nickel smelting is a very specialized application that calls for a 'submerged arc'. Basically, the arc is fairly short and will essentially be submerged in a layer of slag on top of the molten material. It is a semi-continuous process in that periodically, some of molten nickel is poured off. The stream of molten nickel is blasted with water that causes the nickel to solidify into small pellets. Steel melting furnaces, by contrast, involve a much longer arc. The slag layer in the furnace is much thinner, and much of the arc is above the slag. It is a batch process in that once the 'campaign' has been completed, the entire melt is 'tapped' - poured into a tundish either to be cast into ingots or to feed a continuous casting process to make billets, slabs or even plates. There are other smelting processes for other materials - for example, silicon is produced via a smelting process. I would guess that if the voltage requirements of the nickel smelting process are different from the requirements of the original utilization, then it would be necessary that the transformer be redesigned and rewound - something that I would not expect to be very practical.
